DANIEL B. HASELTON, or CHARLESTON, SOUTH CAROLINA.

COTTON-PICKER.

SPECIFICATION formingpart of Letters Patent No. 243,554, datedJ'une 28,1881.

Application filed March 26, 1881.

To all whom it may concern:

Be it known that I, DANIEL B. HASELTON, of Charleston, in the county ofCharleston and State of South Carolina, have invented certain new anduseful Improvements in Cotton- Picking Machines; and I do hereby declarethat the-following is a full, clear, and exact description thereof,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, which form part of this specification.

This invention relates to certain improvements in cotton-pickers, and ithas for its object to provide a machine that will pick and collect thecotton from the bolls, as more fully hereinafter specified. This objectI attain by the apparatus and mechanism illustrated in the accompanyingdrawings, in which Figurel represents a bottomplan view; Fig. 2, a sideelevation; Fig. 3, a central longitudinal section"; Fig. 4, a detailview of one of the picker-disks; Fig. 5, a section through one of thepicker-rolls. Fig. 6 is a top-plan view of my picker. Fig. 7 is adetached sectional view, showing devices for clearing the brushes andcollecting the cleansed cotton.

The letter A indicates the body or frame of my improved machine whichismounted upon the wheels B and B.

The letter A indicates a swinging adj ustable frame. To the forward endof the said frame are secured two forwardly-projectin ggathering-plates, B

The letter 0 indicates the picking-rollers. These are journaled inopposite ends of the frame A, and the rear journals are provided withintermeshing cog-wheels D, one being provided with a pulley, E, whichconnects by means of a chain, F, with a pulley, G, on the shaft U, bymeans of which the picker-rollers are operated. The said rollers consistof a series of serrated steel disks, H, rigidly secured (No model.)

made of wood, will prevent the teeth from seizing substances of anylength, but will per- 7 mit them to seize the cotton in the bolls, theconformation of the disks H enabling them to take the bolls, which areapproximately spherical, and hold them till the cotton is stripped. Thesteel disks on one roller are arranged to work against t-he wooden disksof the other. The rollers vary in diameter at points throughout theirlength, so as to form a sinuous passage between them, to insure thethorough stripping of the cotton from the bolls.

Above the stripping-rollers are located two rollers, N, connecting withthe cog-wheel P on one of the stripper-rollers by means of coggearing R,in such manner as to be rotated faster than saidrollers.

Above the brushes is located a chamber, S, havingforaminous sides andlongitudinalopenings on each side at the top, through which the strippedand cleansed cotton is thrown upward by the brushes and collected on thetop of the chamber. The cotton is cleared from the brushes as theyrevolve by the downwardly-projecting flanges S and delivered into thecarrying-chamber.

The letter it indicates a rod, screw-threaded at its upper end andprovided with an adjusting-nut, V, the lower end being connected to theswinging frame. This rod serves to lift the frame when the apparatus ismoving but not operating.

W indicates a similar screw-rod, having a nut, X, at its end, andconnecting with abellcrank lever, Z, which connects with the rearswinging frame, by means of which it may be elevated.

The height of the body above the ground is to be such as to just clearthe tops of the cotton-plants, and will vary according to the variety ofcotton cultivated.

It will be'observed that, owing to the inclined position of thestripping-rollers, every portion of the plant, from the extreme lowerbranches to the top, is operated upon and thoroughly stripped.

I have shown in connection with my present application a method ofcleaning the cotton preparatory to its being picked, in order to fullyillustrate how the two inventions may be advantageously used inconnection with each other; but as the cleaning mechanism forms matterfor a distinct application, I do not enter now into a detaileddescription of it.

Having thus fully described my invention,

what I claim, and desire to secure by Letters Patent, is-

1. In combination with the swinging frame at the rear, the stripping orpicking rollers and their operating mechanism, substantially as and forthe purposes specified.

2. The stripping-disks having inclined serrations at their peripheries,the said serrations being bent rcarwardly and inwardly at theirextremities, whereby the disks are enabled to freely pass rigidsubstances, while at the same time they will seize the elastic fibers ofthe cotton, substantially as and for the purposes specified.

3. The stripping-rollers consisting of alternate fast and loose disksmounted on suitable shafts, the fast disks being serrated at their edgesand the loose disks bEWGlGd at each side of their peripheries,substantially as and for the purposes specified.

4. In combination with the stripping-roller which the cotton is thrown,to be collected on the top of the chamber, substantially as specified.

In testimony that I claim the foregoing as my own I affix my signaturein presence of two witnesses.

DANIEL B. HASELTON.
